Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
dung cong » dung trong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
chu xanh » chu manh, chua xang, chuc danh
toan cao » toan ban, toan tap
dang va » dang van, dang vat, dung va

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu xanh) OR (chieu xanh)) - anh ((dang va) OR (hang va)) dung cong manh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - anh ((dang va) or (hang va)) dung cong manh toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - anh ((dang va) or (hang va)) dung cong manh toan cao*.
